3.0 GENERAL REQUIREMENTS  3.1 Design Considerations 3.1.1 Unless otherwise noted in the specifications, all pressures and temperatures referred to shall be considered Design Conditions. Design Conditions shall be as defined in Doc. No....

3.1.2 Piping component wall thicknesses are based on pressure design thickness, taking into account the specified corrosion allowance and any permitted manufacturer under tolerance. Piping component wall thickness does not include additional thickness that may be required to compensate for design considerations such as thermal loads due to restraints, live loads, hydraulic shock, loads on underground pipe, or loads or forces from other sources. Additional loads will need to be considered in the design of piping systems.

3.1.3 Unless otherwise indicated in the specifications, piping components are specified to be adequate for the full flange rating of the pressure class.

3.2 Line Class Notes 3.2.1 Each pipe specification contains specific numbered notes (in parenthesis) that pertain to one individual component or to a group of components, as well as a list of additional requirements that pertain to the entire specification.

 

3.2.2 Line class notes are provided in page 4 of this Standard. The information contained in these notes shall be read and adhered to ensure compliance with the line class specification.

3.3 Item Descriptions 3.3.1 The item descriptions on the individual line class are abbreviated, and may be used for purchasing the item with the exception of Valves. Abbreviations are contained in page 4 of this Standard.

3.2.2 The complete purchase description for Valves is contained in the Valve specifications, and shall be followed to ensure compliance with the pipe specifications.

4.0 SPECIFIC REQUIREMENTS  4.1 Pipe 4.1.1 Welded pipe shall not be substituted for seamless pipe. Seamless pipe may be substituted for welded pipe in all services, sizes and materials.

4.1.2 Where "CALC" is specified for piping material wall thickness, the wall thickness shall be calculated in accordance with the applicable ASME B31 Code.

4.1.3 Stainless steel, electric fusion welded (EFW) pipe (ASTM A 358) may be substituted for ASTM A 312 EFW pipe for sizes 14 in. NPS and above. 4.1.4 Carbon steel seamless pipe, ASTM A 106B, may be substituted for ASTM A 53B, Type S, and seamless pipe in all al l sizes.

4.1.5 Where joint factors are specified for pipe, these factors shall be taken as minimum values. Use of pipe with joint factors in excess of these values is acceptable. If pipe manufactured with a higher joint factor than listed on the specification is used, the minimum joint factor listed on the specification shall be used when calculating wall thicknesses of the pipe.

4.1.6 Double Submerged Arc Welded (DSAW) pipe shall be used for all EFW stainless steel pipes. If DSAW pipe is not available, EFW pipe with a single butt joint having a  joint factor factor of 0.80 0.80 shall be used for for 8 in. NPS and smaller. 4.2 Fittings

4.2.2 Dimensions of all fittings shall be in accordance with the industry standard referenced on the individual specification.

4.2.3 Buttweld fittings shall have a wall thickness to match the wall thickness of the adjoining pipe. Fittings of commercially available wall thickness shall be used even though the fitting may have a slightly larger wall thickness than the adjoining pipe. The ends of the fitting shall be taper bored if the thickness of the fittings exceeds that of the pipe by more than 1/16 in. (1.6 mm). Taper boring shall not result in an infringement on the minimum wall thickness.

 

4.2.4 Long radius elbows are required for all buttweld elbows. Short radius elbows shall only be used with "Client" approval. approval.

4.2.5 Use of Lokring® Fittings LOKRING® fittings are generally recognized in the industry as a robust pressure containing device that can be easily and quickly installed without a hot work permit. These features can be highly attractive when considering the installation cost. However, there is limited experience within "Client" on the overall long term performance for these fittings, so the potential for long term reliability and maintenance issues must be considered, such as inspection limitations and the potential for crevice corrosion, water freeze damage and stress corrosion cracking due to the inherent crevice between components and the high sealing stresses. For these reasons LOKRING fittings are considered an acceptable alternative for use in pipe specifications provided all the limitations described below have been met: 1.  Must be approved for the intended service by the local jurisdiction or governing 1.  body for pressure equipment. (Note: ASME B31 proof testing requirements have been satisfied.) 2.  The fittings are used in Category D (as defined in Doc. No...) or utility services as follows: Air, Water, Nitrogen (Outdoor Service Only) and Low pressure steam and condensate service with a maximum design pressure of 200 PSIG. 3.   The applicable pipe specification allows the use of Socket Weld construction for 3. the services described in item 2 above. 4.  Installation shall be only for Carbon Steel piping systems up to 500°F (260°C) and 4.  Stainless Steel piping systems up to 120°F (49°C). 5.  Sizes up to and including 3 in. NPS. 5.  6.   Manufacturer trained and certified personnel must perform the installation 6. utilizing manufacturer approved tool kits and installation procedures. Consult LOKRING® for guidance: www.lokring.com. 7.  These fittings shall not be installed in piping systems which historically have 7.  shown susceptibility to crevice corrosion. 8.  No installations shall be made in service applications with high pulsation or 8.  vibration forces. 9.   No installation in any piping systems that require post weld heat treatment. 9. 10. Fittings 10.  Fittings shall be grit blasted and painted in accordance to Doc. No.... 11. Fittings 11.  Fittings operating below 300°F (149°C) shall be sealed with a temperature resistant silicone caulking to prevent the ingress of water. 12.  After 12. After installation, perform 100% visual inspection to verify the NOGO gage markings are indicating proper installation (marking partially covered), the fitting

 

body protrudes from underneath the swage ring, and remaining gaps are acceptable per the LOKRING® installation procedure.

4.3 Flanges 4.3.1 Dimensions and surface finishes of all flanges shall be in accordance with the industry standard referenced on the individual specification.

4.3.2 Buttweld flanges shall have a wall thickness to match the wall thickness of the adjoining pipe.
